Zirconia Ceramic Bushing is a critical engineering component precision-made from high-performance zirconium oxide (ZrO₂) ceramic material. It is known for its excellent mechanical and physical properties, including extremely high hardness (typically over 1200 HV), excellent wear resistance, and excellent fracture toughness (due to the phase transformation toughening mechanism of zirconium oxide). The bushing has an extremely low coefficient of thermal expansion, ensuring that it maintains dimensional stability over a wide temperature range, and has excellent chemical corrosion resistance, and can resist corrosion from a variety of acids, bases and organic solvents. Its inherent electrical insulation properties also make it essential in applications that require electrical isolation. These combined properties make it a reliable and long-lasting solution for critical locations that are subject to severe mechanical stress, friction and wear or corrosive environments.
In specific applications, Zirconia Ceramic Bushing is often designed to replace traditional metal or polymer bushings to significantly improve equipment performance and life. Its ultra-low coefficient of friction (especially when rubbing against metal) can effectively reduce energy loss during power transmission and reduce wear. Its excellent high-temperature resistance allows it to work stably in environments where metal or plastic materials fail. Whether in high-speed rotating equipment (such as pumps, motors, spindles), linear motion systems subjected to heavy loads or impact loads, chemical equipment in highly corrosive media, or semiconductor manufacturing and biomedical fields that require high cleanliness and non-magnetic environments, this ceramic bushing can provide excellent support, guidance, positioning and isolation functions, and is an ideal choice for those pursuing high reliability, long life and low maintenance costs.
